RE: FCC Takes Action Against WISPs That Interfered with FCC Weather Radar

[Emille Blanc <emille () abccommunications com>]

$25k seems like a cheap fine, really. Have you seen the price of spectrum these days?
And links operating in a licensed spectrum tend to incur $1k per link per year in usage fees.

Said gear almost always has an option to ignore it too, thanks to different regulatory requirements.

North-American operator: Hey, you're actually in India, so don't do DFS on those channels!
Radio equipment: 'Kay.

Queue argument for doing it right and having a link in a non-DFS susceptible channel to survive those many-minute long 
radar event triggered outages.
And counter-argument for the increased costs, so what's the point in using cheap 5GHz radios and spectrum in the first 
place?
Counter-counter-argument that 5GHz gear is so cheap! Such throughput! Wow!

I've seen and heard these stories before, and that's usually how it goes.

Most gear now will hop frequencies automatically if they receive a DFS interference.

If your gear supports this, turn it on.
